Electrical Troubleshooting
Electrical troubleshooting involves checking and resolving an electrical problem (such as when an electrical device stops working correctly). Common troubleshooting practices include checking if the power is on, the bulb has burnt out, or the breaker tripped.

A buss bar essentially acts as a big, thick wire. It exists to distribute electrical power with little resistance and consequently little power loss.
AnswerA 'bus bar' (not'buss' bar) is usually a strip of heavy-duty rectangular-section copper conductor, at line, neutral, or earth potential, to which a number of individual circuit conductors can be connected. It provides a common point of connection for several circuit conductors. The origin of the word, 'bus', comes from 'omnibus' -which means 'providing for many things at once'.

What was the major effect of replacing the two diodes with resistors?
As I have no information on the circuit I can make no valid predictions as to the effect of replacing diodes with resistors. However I assume the effect(s) will resemble that of having very defective diodes in the circuit.
Is there a reset switch on a 2007 Ford Fusion?
yes there is but its under the passenger floorboard by the center console
Can two generator be hook together to make 440 volts?
Not in any way that is easy. Just get a step up transformer from 220 to 440 Volts. Your current will be reduced by about 1/2.
What is the current rating of 25mm 4-core armoured cable?
You have to be specific. whether the conductor is aluminum or copper. Current carrying capacity will be different for these two types. Copper cable can take more load than aluminum cable for same diameter.
As a service electrician, I saw this many times. I would bet a paycheck on the fact that there's a GFI you haven't found yet, or a tripped breaker that doesn't look tripped. Start at your breaker panel. Without forcing them enough to actually turn them off, wiggle the breaker handles slightly to see if one just shoots to the tripped or off position. If none of them are the culprit, it's probably a hidden GFI. Keep in mind the common location for GFI's: Kitchens, bathrooms, garages, and outdoors. Don't think that the second floor GFI can't control the outside receptacles. When it comes to troubleshooting, you'll realize that a lot of wiring routes follow no logic. Also, I've seen many garages lined with stuff to the point that you can't see the walls. You'll have to actually search along the whole wall to find those GFI's. ----
If you do not understand the work well enough to accomplish it yourself properly and safely, don't try it. Consult a professional electrician, as they are proficient enough to do it properly and safely. When working on electrical circuits and equipment, make sure to de-energize the circuit you will be working on. Then test the circuit with a definitive means to make sure it is off. (Multimeter with metal tipped leads, voltage tester with metal tipped leads, etc., not a non-contact tester, which is non-definitive.)
How do you turn off the security light on an Oldsmobile alero?
I've had this problem where I couldn't start my car and it turns out it was because the security light was on. To fix it: Place the key in the ignition and turn it one rotation (so battery is on) then leave it in the ignition for 10 minutes. Restart car and security light will be off.... also car will start!
How do you reset a Chrysler Town and Country ecu?
A mechanic can reset a Chrysler Town and Country ECU for you. If you would rather do it yourself, you will need to purchase a OBD scan tool and follow the prompts.
The headphone jack is actually wired with resistors so the headphones don't get the full amplifiers output. The only way you can fry the speaker system, is to send voltage back through the headphone jack and/or crank the volume all the way up with a short or no speaker connection. Check speaker fuses!

Check your circuit breaker. The receptacle may be malfunctioning or you may be overloading the circuit when trying to do the reset.
Wiring diagram for 1991 Mercedes 500sl?
The wires are connected to each cylinder from the distributor. The distributar cap has an R and an L with a number. Use the L numbers for the drivers side and the R numbers for the other side. Fror example on wire with the labled R2 L3 on the drivers side would terminate at cylinder 3.
Why does wire insulation get hard and break?
The polymers in the plastic insulation oxidize over time and deteriorate, becoming brittle.
Teflon and other modern plastics used for insulation are far more resistant to this process and will last many decades without becoming brittle compared to earlier plastics used before, especially natural rubber (which could become brittle in only a couple of years).

What would cause the outlet plugs in your house to stop working?
You have a loose connection somewhere. It is very common especially if your wiring is aluminum, Because when amperage flows through a conductor it heats up, when something heats ups and cools off it expands and contracts, aluminum has a lower melting temp. than copper there for it expands more so than copper so it will loosen up connections more so than copper...
